The characteristics of solar energetic particles (SEP) as observed in interplanetary space
provide fundamental information about the origin of these particles, and the
acceleration and propagation processes at the Sun and in interplanetary space.
Furthermore, energetic particles provide information on the development and structure
of coronal mass ejections as they propagate from the solar corona into the interplanetary medium. In this paper we review the measurements of energetic particles in interplanetary space and discuss their implication for our understanding of the sources, acceleration and propagation processes.
